The background in today’s photo is very far away — the tree where this lovely bird was singing stands on a hill, and down the slope are miles and miles of flats, with the village of Pulborough visible in the distance. I think the full (uncropped) photo does a good job of showing that depth between foreground and background — whereas any reasonable crop that makes the bird look bigger than an ant kind of ruins it. The best crop I managed is shown above, and here is the original.
